Description

本発明は、液晶装置などを備えた表示装置、該表示装置の製造方法、および当該表示装置を備えた電子機器に関するものである。   The present invention relates to a display device including a liquid crystal device, a method for manufacturing the display device, and an electronic device including the display device.

携帯電話、カーナビゲーション、パーソナルコンピュータ、券売機、銀行の端末などの電子機器に用いられる表示装置では、液晶装置などの画像生成装置から表示光が出射される出射面に対して、タッチパネルやカバーガラスなどの透光部材が貼られた構造が採用される。   In display devices used in electronic devices such as mobile phones, car navigation systems, personal computers, ticket vending machines, bank terminals, etc., a touch panel or cover glass is provided on the exit surface from which display light is emitted from an image generating device such as a liquid crystal device. A structure in which a translucent member such as is attached is adopted.

しかしながら、画像生成装置の出射面に対して透光部材を接着剤により貼った場合、接着剤については厚く形成することができないため、透光部材が押圧されたとき、画像生成装置に過大な力が加わるなど、耐衝撃性が低い。また、画像生成装置としてカラー表示用に液晶装置を用いた場合、透光部材が押圧されたときに液晶パネルが撓んで、色ムラなどが発生する原因となる。さらに、接着剤の場合、硬化時の収縮や、硬化後に吸湿した場合の膨潤によって、液晶パネルに力が加わって撓み、色ムラなどが発生する原因となる。   However, when the translucent member is attached to the exit surface of the image generating apparatus with an adhesive, the adhesive cannot be formed thick, and therefore, when the translucent member is pressed, an excessive force is applied to the image generating apparatus. Impact resistance is low. Further, when a liquid crystal device is used for color display as the image generating device, the liquid crystal panel is bent when the light transmitting member is pressed, which causes color unevenness. Further, in the case of an adhesive, due to shrinkage during curing and swelling when moisture is absorbed after curing, a force is applied to the liquid crystal panel, which may cause bending and color unevenness.

一方、液晶装置にタッチパネルを貼るにあたって粘着剤を用いることが提案されている（特許文献１参照）。   On the other hand, it has been proposed to use an adhesive to attach a touch panel to a liquid crystal device (see Patent Document 1).

粘着剤であれば、貼り直しが可能であるとともに、かなりの厚さに形成することもできる。
特開２００４−５５４０号公報 If it is an adhesive, it can be reattached and can be formed to a considerable thickness.
JP 2004-5540 A

しかしながら、粘着剤を用いた場合には、大面積同士を貼り合わせると、気泡が入りやすいという問題があり、画像生成装置と透光部材との間に気泡が入ると、表示した画像の品位が低下してしまう。   However, when the adhesive is used, there is a problem that bubbles are likely to enter when the large areas are bonded together. If bubbles enter between the image generating device and the translucent member, the quality of the displayed image is deteriorated. It will decline.

以上の問題点に鑑みて、本発明の課題は、十分な厚さの接合材料層で画像生成装置と透光部材とを貼り合わせることができるとともに、気泡の入り込みを防止することのできる表示装置、該表示装置の製造方法、および当該表示装置を備えた電子機器を提供することにある。   In view of the above problems, an object of the present invention is to provide a display device that can bond an image generating device and a light-transmitting member with a bonding material layer having a sufficient thickness and can prevent bubbles from entering. An object of the present invention is to provide a method for manufacturing the display device, and an electronic apparatus including the display device.

上記課題を解決するために、本発明では、表示光を出射する出射面を有した画像生成装置と、前記画像生成装置の前記出射面と重ねて配置された入射面を有する透光部材と、を備え、前記出射面と前記入射面とが、透光性の粘着剤層と、透光性の接着剤層と、を介在させて貼り合わされており、前記接着材層は、前記粘着剤層よりも厚さが薄い硬化型接着剤とされていることを特徴とする。
In order to solve the above-described problem, in the present invention, an image generation device having an emission surface that emits display light, and a light-transmissive member that has an incident surface that is arranged to overlap the emission surface of the image generation device, The light emitting surface and the light incident surface are bonded together with a light-transmitting pressure-sensitive adhesive layer and a light-transmitting adhesive layer interposed therebetween, and the adhesive layer is formed of the pressure-sensitive adhesive layer. It is characterized in that the curable adhesive is thinner than that.

本発明では、表示光を出射する出射面を有した画像生成装置と、前記画像生成装置の前記出射面と重ねて配置された入射面を有する透光部材と、を備え、前記出射面と前記入射面とが、透光性の粘着剤層と、透光性の接着剤層と、を介在させて貼り合わされた表示装置の製造方法であって、前記出射面および前記入射面のうちの一方の面上に透光性の粘着剤層を形成する粘着剤層形成工程と、前記粘着剤層の上面、又は、前記出射面および前記入射面のうちの他方の面上に、硬化型接着剤を形成する硬化型接着剤形成工程と、前記画像生成装置と前記透光部材とを前記粘着剤層と前記硬化型接着剤層とを介在させて貼り合わせる接着工程と、を有することを特徴とする。
In the present invention, comprising: an image generation device having an emission surface for emitting display light ; and a translucent member having an incident surface arranged to overlap the emission surface of the image generation device, the emission surface and the The incident surface is a method of manufacturing a display device in which a light-transmitting pressure-sensitive adhesive layer and a light-transmitting adhesive layer are interposed, and one of the light exit surface and the light incident surface A pressure-sensitive adhesive layer forming step of forming a light-transmitting pressure-sensitive adhesive layer on the surface of the adhesive, and a curable adhesive on the upper surface of the pressure-sensitive adhesive layer or the other surface of the exit surface and the incident surface a curable adhesive forming a, and wherein a, a bonding step and the translucent member and the image generation device is interposed between the curable adhesive layer and the adhesive layer bonding To do .

本発明において、「接着」とは「被接合面と接合材料が一体化した状態」であり、「粘着」とは「接着の一種であるが、水、溶剤、熱などを使用せず、常温で短時間、わずかな圧力を加えるだけで接合した状態」の意味である。また、「接着剤」は、貼り合わせるときには流動性のある液体であり、被接合面に容易に接触し、濡れることができ、その後、加熱や化学反応により固体に変化し、剥離に抵抗する力を発揮する。これに対して、「粘着剤」は、貼り合せるときもゲル状の柔らかい固体で、そのままの状態で被接合面に濡れ、その後も、態の変化を起こさず剥離に抵抗する。   In the present invention, “adhesion” is “a state in which the joining surface and the bonding material are integrated”, and “adhesion” is “a kind of adhesion, but does not use water, solvent, heat, etc. It means “joined state by applying a slight pressure for a short time”. An “adhesive” is a fluid liquid when bonded together, and can easily contact and get wet with the surfaces to be joined, and then changes to a solid by heating or chemical reaction, and resists peeling. Demonstrate. On the other hand, the “adhesive” is a gel-like soft solid even when bonded, wets the bonded surface as it is, and resists peeling without causing any change in the state thereafter.

本発明では、画像生成装置の出射面と透光部材の入射面とを貼り合わせるにあたって、粘着剤層と接着剤とを併用するため、以下の理由から、十分な厚さの接合材料層（粘着剤層および接着剤）で画像生成装置と透光部材とを貼り合わせることができるとともに、気泡が入り込みにくい。接着剤は、気泡が入り込みにくいという長所があるが、厚く形成できないという短所を有する一方、粘着剤層は、厚く形成できるという長所を有するが、気泡が入り込みやすいという短所を有しており、本発明では、これらの接合材料を併用する。このため、厚さについては粘着剤層で確保することができるとともに、粘着剤層と他方の面との間に接着剤で確実に埋められるので、気泡が入り込まない。それ故、外部から透光部材に力が加わっても、かかる力については厚い粘着剤層で吸収され、画像生成装置に過大な力が伝わらない。また、接着剤層については無理に厚くする必要がないので、例え、硬化時の収縮や、硬化後の吸湿に起因する膨潤が発生しても、かかる変形に起因する力が小さいので、画像生成装置に大きな力が加わらない。それ故、品位の高い画像を表示することができるとともに、表示装置の信頼性を向上することができる。   In the present invention, the adhesive layer and the adhesive are used together when the emission surface of the image generating device and the incident surface of the light transmitting member are bonded together. The image generation device and the translucent member can be bonded together with the agent layer and the adhesive, and bubbles are difficult to enter. Adhesives have the advantage that bubbles do not easily enter, but have the disadvantage that they cannot be formed thick, while the adhesive layer has the advantage that it can be formed thick, but has the disadvantage that bubbles easily enter. In the invention, these bonding materials are used in combination. For this reason, the thickness can be secured by the pressure-sensitive adhesive layer, and since it is reliably filled with the adhesive between the pressure-sensitive adhesive layer and the other surface, bubbles do not enter. Therefore, even if a force is applied to the translucent member from the outside, the force is absorbed by the thick adhesive layer, and an excessive force is not transmitted to the image generating apparatus. In addition, since it is not necessary to forcefully thicken the adhesive layer, even if shrinkage during curing or swelling due to moisture absorption after curing occurs, the force due to such deformation is small, so image generation No great force is applied to the device. Therefore, a high-quality image can be displayed and the reliability of the display device can be improved.

本発明において、前記粘着剤層は、粘着シート（粘着剤をシート状としたもの）からなることが好ましい。この場合、前記粘着剤層形成工程において、前記一方の面上に前記粘着剤層を形成するにあたっては、前記粘着剤層としての粘着シートを前記出射面上に貼ることになる。このように構成すると、粘着剤を塗布する必要がないので、前記一方の面上に前記粘着剤層を容易に形成することができるとともに、粘着剤層を一定の厚さに形成することができる。

In this invention, it is preferable that the said adhesive layer consists of an adhesive sheet (what used the adhesive as a sheet form). In this case, in forming the pressure-sensitive adhesive layer on the one surface in the pressure-sensitive adhesive layer forming step, a pressure-sensitive adhesive sheet as the pressure-sensitive adhesive layer is pasted on the emission surface. If comprised in this way, since it is not necessary to apply | coat an adhesive, while being able to form the said adhesive layer easily on said one surface, an adhesive layer can be formed in fixed thickness. .

本発明において、前記一方の面は前記出射面であり、前記他方の面は前記入射面であることが好ましい。すなわち、画像生成装置の出射面上に粘着剤層が形成され、粘着剤層と透光部材との間に接着剤層が位置することが好ましい。このような構成は、本発明を適用した表示装置の製造方法において、前記粘着剤層形成工程で前記粘着剤層を前記出射面上に形成することにより実現することができる。このように構成すると、接着剤において、硬化時の収縮や、硬化後の吸湿に起因する膨潤が発生しても、かかる変形に起因する力は粘着剤層によって吸収されるので、画像生成装置に大きな力が加わらない。それ故、品位の高い画像を表示することができるとともに、表示装置の信頼性をさらに向上することができる。   In the present invention, it is preferable that the one surface is the emission surface and the other surface is the incident surface. That is, it is preferable that a pressure-sensitive adhesive layer is formed on the exit surface of the image generation apparatus, and the adhesive layer is located between the pressure-sensitive adhesive layer and the light-transmissive member. Such a configuration can be realized by forming the pressure-sensitive adhesive layer on the emission surface in the pressure-sensitive adhesive layer forming step in the method for manufacturing a display device to which the present invention is applied. With this configuration, even when the adhesive shrinks during curing or swells due to moisture absorption after curing, the force resulting from the deformation is absorbed by the adhesive layer, so that the image generating apparatus Big power is not applied. Therefore, a high-quality image can be displayed and the reliability of the display device can be further improved.

本発明は、前記画像生成装置が液晶装置である場合に適用すると、特に効果的である。液晶装置の場合、一対の基板間に液晶層が保持されているので、大きな力が加わると、基板間隔が変動して画像の品位が低下するなどの問題が発生しやすいが、本発明を適用すると、かかる問題の発生を確実に防止することができる。   The present invention is particularly effective when applied to the case where the image generating apparatus is a liquid crystal device. In the case of a liquid crystal device, since a liquid crystal layer is held between a pair of substrates, if a large force is applied, problems such as fluctuations in the distance between the substrates and deterioration in image quality are likely to occur. Then, the occurrence of such a problem can be reliably prevented.

本発明において、前記透光部材は、例えば、カバーガラス、あるいはタッチパネルに用いた透光性基板である。   In the present invention, the translucent member is, for example, a cover glass or a translucent substrate used for a touch panel.

本発明を適用した表示装置の製造方法では、前記硬化型接着剤形成工程において、前記硬化型接着剤の塗布装置は、前記粘着剤層に非接触な状態で、前記粘着剤層の上面に前記硬化型接着剤を塗布することが好ましい。すなわち、前記粘着剤層の側に前記接着剤を塗布する場合、粘着剤層の表面は粘着性を有しているので、接着剤の塗布装置が粘着剤層に非接触状態にあることが好ましい。それ故、塗布装置としては、ノズルから接着剤を吐出、滴下する方式が好ましい。

In the method for manufacturing a display device to which the present invention is applied, in the curable adhesive forming step, the curable adhesive coating device is in contact with the pressure-sensitive adhesive layer, and is disposed on the upper surface of the pressure-sensitive adhesive layer. It is preferable to apply a curable adhesive . That is, when the adhesive is applied to the pressure-sensitive adhesive layer side, the surface of the pressure-sensitive adhesive layer has adhesiveness, and therefore the adhesive application device is preferably in a non-contact state with the pressure-sensitive adhesive layer. . Therefore, as a coating apparatus, a method of discharging and dropping an adhesive from a nozzle is preferable.

本発明を適用した表示装置の製造方法では、前記接着工程において、前記他方の面上に前記接着剤を塗布するにあたっては、当該接着剤の塗布装置が当該他方の面に接触してもよい。すなわち、前記他方の面側に前記接着剤を塗布する場合、粘着剤層と違って当該他方の面に粘着性がないので、接着剤の塗布装置が前記他方の面に接触してもよい。それ故、塗布装置としては、スクリーン印刷装置や転写装置などを用いることができ、かかる装置によれば、所定領域に接着剤を正確に塗布することができる。   In the method for manufacturing a display device to which the present invention is applied, in the bonding step, when the adhesive is applied onto the other surface, the adhesive application device may contact the other surface. That is, when the adhesive is applied to the other surface side, unlike the pressure-sensitive adhesive layer, the other surface is not sticky, so that the adhesive application device may be in contact with the other surface. Therefore, a screen printing device, a transfer device, or the like can be used as the coating device, and according to such a device, the adhesive can be accurately applied to a predetermined area.

本発明を適用した表示装置は、携帯電話、カーナビゲーション、パーソナルコンピュータ、券売機、銀行の端末などの電子機器に用いることができる。   A display device to which the present invention is applied can be used for electronic devices such as a mobile phone, a car navigation system, a personal computer, a ticket machine, and a bank terminal.

In the drawings to be referred to in the following description, the scales are different for each layer and each member so that each layer and each member have a size that can be recognized on the drawing.

（液晶装置５と透光部材１０との接合構造）
このように構成した表示装置１００において、液晶装置５の出射面５３（第１偏光板８１において表示光が出射される側の面）と、透光部材１０の入射面１３（表示光が出射される側とは反対側の面）とは、以下に説明する構造をもって、略全面で接合されている。 (Junction structure of the liquid crystal device 5 and the translucent member 10)
In the display device 100 configured as described above, the emission surface 53 of the liquid crystal device 5 (the surface on the side where the display light is emitted in the first polarizing plate 81) and the incident surface 13 of the light transmitting member 10 (the display light is emitted). The surface opposite to the first side) has a structure to be described below and is joined substantially over the entire surface.

まず、液晶装置５の出射面５３（本形態における一方面）上には、透光性の粘着剤層２１が形成されている。また、粘着剤層２１と透光部材１０の入射面１３（本形態における他方面）とは、接着剤層２２とによって接着されている。ここで、接着剤層２２は、厚さが５〜１００μｍのＵＶ（紫外線）硬化型のアクリル樹脂系接着剤からなり、透光性を備えている。また、粘着剤層２１は、厚さが５０〜５００μｍのアクリル樹脂系の粘着シート（粘着剤をシート状としたもの）からなる。   First, the light-transmitting pressure-sensitive adhesive layer 21 is formed on the emission surface 53 (one surface in the present embodiment) of the liquid crystal device 5.

Here, the adhesive layer 22 is made of a UV (ultraviolet) curable acrylic resin adhesive having a thickness of 5 to 100 μm and has translucency. Further, the pressure-sensitive adhesive layer 21 is made of an acrylic resin-based pressure-sensitive adhesive sheet (thickness of the pressure-sensitive adhesive made into a sheet) having a thickness of 50 to 500 μm.

（表示装置１００の製造方法）
図３は、本発明の実施の形態１に係る表示装置１００の製造工程のうち、液晶装置５と透光部材１０との接合工程を示す工程断面である。 (Manufacturing method of display device 100)
FIG. 3 is a process cross-section illustrating a bonding process between the liquid crystal device 5 and the translucent member 10 in the manufacturing process of the display device 100 according to Embodiment 1 of the present invention.

本形態では、液晶装置５の出射面５３と透光部材１０の入射面１３とを接合するにあたって、まず、図３（ａ）に示すように、液晶パネル５ａに対して、第２偏光板８２を接着剤や粘着剤（図示せず）により貼った状態とする。この状態で、第１偏光板８１は未だ貼られていない。   In this embodiment, in joining the exit surface 53 of the liquid crystal device 5 and the entrance surface 13 of the translucent member 10, first, as shown in FIG. 3A, the second polarizing plate 82 with respect to the liquid crystal panel 5a. Is in a state pasted with an adhesive or a pressure-sensitive adhesive (not shown). In this state, the first polarizing plate 81 is not yet applied.

そして、図３（ａ）、（ｂ）に示す粘着剤層形成工程では、液晶パネル５ａにおいて表示光を出射する側の面に接着剤や粘着剤（図示せず）により第１偏光板８１を貼る。その際、第１偏光板８１については、予め、剥離シート２１ａ上に形成されている粘着剤層２１（粘着シート）に対して第１偏光板８１を粘着させた状態にしておき、液晶パネル５ａに対して第２偏光板８２を貼った後、剥離シート２１ａを剥がす。   In the pressure-sensitive adhesive layer forming step shown in FIGS. 3A and 3B, the first polarizing plate 81 is applied to the surface of the liquid crystal panel 5a on the side from which display light is emitted with an adhesive or a pressure-sensitive adhesive (not shown). Paste. In that case, about the 1st polarizing plate 81, the 1st polarizing plate 81 is made to adhere to the adhesive layer 21 (adhesive sheet) currently formed on the peeling sheet 21a beforehand, and the liquid crystal panel 5a is set. After the second polarizing plate 82 is pasted, the release sheet 21a is peeled off.

その結果、液晶装置５の出射面５３上（第１偏光板８１において表示光が出射される側の面上）に透光性の粘着剤層２１（粘着シート）が貼られた状態が形成された状態となる。このような方法で粘着剤層２１を形成すると、粘着剤を塗布する必要がないので、粘着剤層２１を容易に形成することができるとともに、粘着剤層２１を一定の厚さに形成することができる。   As a result, a state is formed in which the light-transmitting pressure-sensitive adhesive layer 21 (pressure-sensitive adhesive sheet) is pasted on the light emission surface 53 of the liquid crystal device 5 (on the surface on the side where the display light is emitted in the first polarizing plate 81). It becomes a state. When the pressure-sensitive adhesive layer 21 is formed by such a method, it is not necessary to apply the pressure-sensitive adhesive. Therefore, the pressure-sensitive adhesive layer 21 can be easily formed, and the pressure-sensitive adhesive layer 21 is formed to have a constant thickness. Can do.

次に、図３（ｃ）に示す接着工程では、粘着剤層２１の上面に接着剤２２ａを塗布する。その際、粘着剤層２１の表面は粘着性を有しているので、ノズルから接着剤２２ａを吐出、滴下する方式の塗布装置のように、粘着剤層２１に塗布装置が非接触状態にあることが好ましい。次に、接着剤２２ａの上に透光部材１０を重ねて、粘着剤層２１と透光部材１０の入射面１３との間で接着剤２２ａを薄く展開させる。その際、透光部材１０の入射面１３では、周りに遮光層１１に起因する段差があるので、接着剤２２ａは所定の領域内で一定の厚さに展開される。次に、接着剤２２ａにＵＶ光を照射して、接着剤２２ａを硬化させる。その結果、図２に示すように、液晶装置５の出射面５３と透光部材１０の入射面１３とは、出射面５３上に形成された透光性の粘着剤層２１と、入射面１３と粘着剤層２１とを接着する透光性の接着剤層２２とによって貼り合わされた構造となる。   Next, in the bonding step shown in FIG. 3C, an adhesive 22 a is applied to the upper surface of the pressure-sensitive adhesive layer 21. At that time, since the surface of the pressure-sensitive adhesive layer 21 has adhesiveness, the coating device is in a non-contact state with the pressure-sensitive adhesive layer 21 like a coating device that discharges and drops the adhesive 22a from the nozzle. It is preferable. Next, the translucent member 10 is overlaid on the adhesive 22 a, and the adhesive 22 a is spread thinly between the pressure-sensitive adhesive layer 21 and the incident surface 13 of the translucent member 10. At this time, since there is a step due to the light shielding layer 11 on the incident surface 13 of the light transmissive member 10, the adhesive 22a is spread to a constant thickness within a predetermined region. Next, the adhesive 22a is irradiated with UV light to cure the adhesive 22a. As a result, as shown in FIG. 2, the exit surface 53 of the liquid crystal device 5 and the entrance surface 13 of the translucent member 10 include the translucent adhesive layer 21 formed on the exit surface 53 and the entrance surface 13. And a light-transmitting adhesive layer 22 that bonds the adhesive layer 21 to each other.

以上説明したように、本形態では、液晶装置５の出射面５３と透光部材１０の入射面１３とを貼り合わせるにあたって、粘着剤層２１と接着剤層２２とを併用するため、以下の理由から、十分な厚さの接合材料層２０（粘着剤層２１および接着剤層２２）で液晶装置５と透光部材１０とを貼り合わせることができるとともに、間に気泡が入り込みにくい。接着剤２２ａは、気泡が入り込みにくいという長所があるが、厚く形成できないという短所を有する一方、粘着剤層２１は、厚く形成できるという長所を有するが、気泡が入り込みやすいという短所を有している。本形態では、これらの接合材料（粘着剤層２１および接着剤層２２）を併用する。このため、接合材料層２０の厚さについては粘着剤層２１で、少なくとも３０μｍ以上確保することができるとともに、粘着剤層２１と透光部材１０の入射面１３との間は接着剤２２ａで確実に埋められるので、気泡が入り込まない。 (Main effects of this form)
As described above, in this embodiment, the adhesive layer 21 and the adhesive layer 22 are used in combination when the emission surface 53 of the liquid crystal device 5 and the incident surface 13 of the translucent member 10 are bonded together. Therefore, the liquid crystal device 5 and the translucent member 10 can be bonded to each other with a sufficient thickness of the bonding material layer 20 (the pressure-sensitive adhesive layer 21 and the adhesive layer 22), and bubbles are less likely to enter therebetween. The adhesive 22a has an advantage that bubbles do not easily enter, but has an advantage that it cannot be formed thick. On the other hand, the adhesive layer 21 has an advantage that it can be formed thick, but has an advantage that bubbles easily enter. . In this embodiment, these bonding materials (the pressure-sensitive adhesive layer 21 and the adhesive layer 22) are used in combination. For this reason, the thickness of the bonding material layer 20 can be secured at least 30 μm or more with the pressure-sensitive adhesive layer 21, and the adhesive 22 a is surely provided between the pressure-sensitive adhesive layer 21 and the incident surface 13 of the translucent member 10. Because it is buried in, bubbles do not enter.

それ故、外部から透光部材１０に力が加わっても、かかる力については厚い粘着剤層２１で吸収され、液晶装置５に過大な力が伝わらない。また、接着剤層２２については無理に厚くする必要がないので、例え、硬化時の収縮や、硬化後の吸湿に起因する膨潤が発生しても、かかる変形に起因する力が小さいので、液晶装置５に大きな力が加わらない。   Therefore, even if a force is applied to the translucent member 10 from the outside, the force is absorbed by the thick adhesive layer 21 and an excessive force is not transmitted to the liquid crystal device 5. Further, since it is not necessary to forcefully increase the thickness of the adhesive layer 22, even if the shrinkage during the curing or the swelling due to the moisture absorption after the curing occurs, the force due to the deformation is small, so the liquid crystal A large force is not applied to the device 5.

しかも、液晶装置５の出射面５３上に粘着剤層２１が形成され、粘着剤層２１と透光部材１０との間に接着剤層２２が位置するため、接着剤層２２において、硬化時の収縮や、硬化後の吸湿に起因する膨潤が発生しても、かかる変形に起因する力は粘着剤層２１によって吸収されるので、液晶装置５に大きな力が加わらない。それ故、液晶装置１０において素子基板５０と対向基板６０との間隔が変動して画像の品位が低下するなどの問題が発生しない。それ故、本形態によれば、品位の高い画像を表示することができるとともに、表示装置１００の信頼性をさらに向上することができる。   In addition, since the pressure-sensitive adhesive layer 21 is formed on the emission surface 53 of the liquid crystal device 5 and the adhesive layer 22 is located between the pressure-sensitive adhesive layer 21 and the translucent member 10, Even if shrinkage or swelling due to moisture absorption after curing occurs, the force resulting from such deformation is absorbed by the pressure-sensitive adhesive layer 21, so that a large force is not applied to the liquid crystal device 5. Therefore, in the liquid crystal device 10, there is no problem that the distance between the element substrate 50 and the counter substrate 60 fluctuates and the image quality deteriorates. Therefore, according to this embodiment, a high-quality image can be displayed, and the reliability of the display device 100 can be further improved.

［実施の形態２］
図４は、本発明の実施の形態２に係る表示装置１００の製造工程のうち、液晶装置５と透光部材１０との接合工程を示す工程断面である。なお、本形態の基本的な構成は実施の形態１と同様であるため、共通する部分には同一の符号を付して図示し、それらの説明を省略する。 [Embodiment 2]
FIG. 4 is a process cross-section illustrating a bonding process between the liquid crystal device 5 and the translucent member 10 in the manufacturing process of the display device 100 according to the second embodiment of the present invention. Since the basic configuration of this embodiment is the same as that of Embodiment 1, common portions are denoted by the same reference numerals and description thereof is omitted.

本形態の表示装置１００においでも、実施の形態１と同様、液晶装置５の出射面５３（第１偏光板８１において表示光が出射される側の面）と、透光部材１０の入射面１３（表示光が出射される側とは反対側の面）とは、出射面５３上に形成された透光性の粘着剤層２１と、入射面１３と粘着剤層２１とを接着する透光性の接着剤層２２とによって略全面で貼り合わされている。ここで、接着剤層２２は、厚さが５〜１００μｍのＵＶ硬化型アクリル樹脂系接着剤からなり、粘着剤層２１は、厚さが５０〜５００μｍのアクリル樹脂系の粘着シート（粘着剤をシート状としたもの）からなる。   Also in the display device 100 of the present embodiment, as in the first embodiment, the emission surface 53 of the liquid crystal device 5 (the surface on the side where the display light is emitted in the first polarizing plate 81) and the incident surface 13 of the translucent member 10. (The surface opposite to the side from which the display light is emitted) is a light-transmitting pressure-sensitive adhesive layer 21 formed on the light-emitting surface 53, and a light-transmitting property that bonds the incident surface 13 and the pressure-sensitive adhesive layer 21 together. The adhesive layer 22 is bonded to substantially the entire surface. Here, the adhesive layer 22 is made of a UV curable acrylic resin adhesive having a thickness of 5 to 100 μm, and the adhesive layer 21 is an acrylic resin adhesive sheet (adhesive) having a thickness of 50 to 500 μm. Sheet).

本形態では、液晶装置５の出射面５３と透光部材１０の入射面１３とを接合するにあたって、まず、図４（ａ）に示すように、液晶パネル５ａに対して、第２偏光板８２を接着剤や粘着剤（図示せず）により貼った状態とする。この状態で、第１偏光板８１は未だ貼られていない。   In this embodiment, when joining the exit surface 53 of the liquid crystal device 5 and the entrance surface 13 of the translucent member 10, first, as shown in FIG. 4A, the second polarizing plate 82 is applied to the liquid crystal panel 5a. Is in a state pasted with an adhesive or a pressure-sensitive adhesive (not shown). In this state, the first polarizing plate 81 is not yet applied.

そして、図４（ａ）、（ｂ）に示す粘着剤層形成工程では、液晶パネル５ａにおいて表示光を出射する側の面に接着剤や粘着剤（図示せず）により第１偏光板８１を貼る。その際、第１偏光板８１については、予め、剥離シート２１ａ上に形成されている粘着剤層２１（粘着シート）に対して第１偏光板８１を粘着させた状態にしておき、液晶パネル５ａに対して第２偏光板８２を貼った後、剥離シート２１ａを剥がす。その結果、液晶装置５の出射面５３上に透光性の粘着剤層２１（粘着シート）が貼られた状態が形成された状態となる。   In the pressure-sensitive adhesive layer forming step shown in FIGS. 4A and 4B, the first polarizing plate 81 is applied to the surface of the liquid crystal panel 5a on the side from which display light is emitted with an adhesive or a pressure-sensitive adhesive (not shown). Paste. In that case, about the 1st polarizing plate 81, the 1st polarizing plate 81 is made to adhere to the adhesive layer 21 (adhesive sheet) currently formed on the peeling sheet 21a beforehand, and the liquid crystal panel 5a is set. After the second polarizing plate 82 is pasted, the release sheet 21a is peeled off. As a result, a state in which the light-transmitting pressure-sensitive adhesive layer 21 (pressure-sensitive adhesive sheet) is pasted on the emission surface 53 of the liquid crystal device 5 is formed.

次に、図４（ｃ）に示す接着工程では、透光部材１０において遮光層１１で囲まれた領域内接着剤２２ａを塗布する。その際、粘着剤層２１と違って透光部材１０の入射面１３には粘着性がないので、接着剤２２ａの塗布装置が入射面１３に接触してもよい。それ故、塗布装置としては、スクリーン印刷装置や転写装置などを用いることができ、かかる装置によれば、所定領域に接着剤２２ａを正確に塗布することができる。次に、透光部材１０において、接着剤２２ａが形成された入射面１３を粘着剤層２１に重ね、この状態で、接着剤２２ａにＵＶを照射して接着剤２２ａを硬化させる。その結果、図２に示すように、液晶装置５の出射面５３と透光部材１０の入射面１３とは、出射面５３上に形成された透光性の粘着剤層２１と、入射面１３と粘着剤層２１とを接着する透光性の接着剤層２２とによって貼り合わされた構造となる。   Next, in the bonding step shown in FIG. 4C, the in-region adhesive 22 a surrounded by the light shielding layer 11 in the translucent member 10 is applied. At this time, unlike the pressure-sensitive adhesive layer 21, the incident surface 13 of the translucent member 10 does not have adhesiveness, and thus the coating device for the adhesive 22 a may come into contact with the incident surface 13. Therefore, a screen printing device, a transfer device, or the like can be used as the coating device, and according to such a device, the adhesive 22a can be accurately applied to a predetermined area. Next, in the translucent member 10, the incident surface 13 on which the adhesive 22a is formed is superimposed on the pressure-sensitive adhesive layer 21, and in this state, the adhesive 22a is irradiated with UV to cure the adhesive 22a. As a result, as shown in FIG. 2, the exit surface 53 of the liquid crystal device 5 and the entrance surface 13 of the translucent member 10 include the translucent adhesive layer 21 formed on the exit surface 53 and the entrance surface 13. And a light-transmitting adhesive layer 22 that bonds the adhesive layer 21 to each other.

このように構成した場合も、実施の形態１と同様、粘着剤層２１と接着剤層２２とを併用した接合材料層２０を用いたので、接合材料層２０を厚く形成した場合でも、気泡が入り込まないなど、実施の形態１と同様な効果を奏する。   Even in this configuration, as in the first embodiment, since the bonding material layer 20 using the pressure-sensitive adhesive layer 21 and the adhesive layer 22 is used, even when the bonding material layer 20 is formed thick, bubbles are generated. There are the same effects as in the first embodiment, such as not entering.
